IOS——定位单元格子视图

方法一：

在表格的某行添加按钮时，可以根据一下方法获取到表格的NSIndexPath

- (void)btnClicked:(id)sender event:(id)event{
    NSSet *touches = [event allTouches];
    UITouch *touch = [touches anyObject];
    CGPoint currentTouchPosition = [touch locationInView:[self myTableView]];
    NSIndexPath *indexPath = [[self myTableView] indexPathForRowAtPoint:currentTouchPosition];
    //do something
}

方法二：

- (void)cellBUttonTapped:(id)sender{
    UIButton *button = sender;
    CGPoint correctedPoint = [button convertPoint:button.bounds.origin toView:self.tableView];
    NSIndexPath *indexPath = [self.tableView indexPathForAtPoint:correctedPoint];
    NSLog(@"%d",indexPath.row);
}
